Description

technical field [0001] The invention relates to a ship power device, in particular to a ship hybrid power device. Background technique [0002] With the increasingly stringent maritime discharge regulations, the issue of ship pollutant discharge has attracted more and more attention from the shipping departments of various countries. Moreover, the continuous development of global trade also puts forward higher requirements for the carrying capacity of ships. Although the traditional diesel engine propulsion method can quickly meet the load demand of the ship during navigation, it has disadvantages such as low energy utilization rate, excessive fuel consumption and excessive noise during operation. Although electric propulsion has the advantages of cleanliness, fast response, and high operating efficiency, it has disadvantages such as poor battery life, frequent switching of working conditions, easy damage to the ship's power grid, and high operation and maintenance costs. ...
